I think you're assuming things about his network topology that may not be true. The basic explanation is right, though - you've got two boxes trying to use that IP address on different networks. > The messages won't affect your network, but if you don't want to see > them, change your network addresses to something a little less common, > such as "192.168.53.x"... If it's actually coming from outside your local network, your should configure your firewall to throw them away. Anything coming from your outside world claiming to be from the local network, or one of the various reserved networks should be thrown away. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
